Estimation of genetic parameters for a new model for defining body structure scores (frame scores) in Nellore cattle
, “Estimation of genetic parameters for a new model for defining body structure scores (frame scores) in Nellore cattle”, vol. 5, pp. 828-836, 2006.
Models for estimation of frame scores in Nellore beef cattle (FRAME_GMA) were developed, comparing them with frame scores estimated using equations proposed by the Beef Improvement Federation (FRAME_BIF, USA). Correlation among frame scores obtained by these two methodologies, along with the independent variables considered in the estimation models, were also studied. A data set with 12,728 animals, with ages between 490 and 610 days, was used. The models that best adjusted to FRAME_GMA included hip height, weight and interaction between height and weight.
